RECEPTAGLES CONTAINING GASOLENE.

Specification of Letters Patent. Patented May 20, 1919 Application filed July 17, 1917. Serial No. 180,972.

tain gaseous or vaporous fluids, as for ex-- ample, gasolene.

The prime object of the invention is to provide a simple and eflicient device of the character mentioned designed to prevent the waste of the vaporsor fluid when tapping the contents of the receptacle.

A further object of the invention is to provide a device of such'class, in a manner as hereinafter set forth, for supplying air to the receptacle when occasion so requires, to facilitate the discharge of gasolene.

Further objects of the invention are to provide a tap of the class referred to, which is simple in its construction and arrangement, strong, durable, thoroughly eflicient, conveniently adjusted and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts, as hereinafter referred to, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a part elevational and a part vertical sectional View of a tap device constructed in accordance with this invention;

Fig. 2, a detail vertical sectional view particularly showing the bung element ofthe tap;

Fig. '3, a view similar to Fig. 2 particularly showing the plug of the bung element adjusted; and p Fig. 4, a part elevational and a part sectional view of the tap device in operative position, certain of the elements being omitte A tap in accordance with this invention,

fment and a discharge element.

The head of the barrel, drum or receptacle, hereinafter termed barrel, is indicated at 1, and which is provided with a hung hole 2, havlng the wall thereof threaded.

The bung element consists of a disk 3, having a centrally disposed opening 4, with the wall thereof threaded. The disk 3, has peripheral threads 5, which havethreaded engagement with the threads of the wall of the opemng 2, for securing the disk in the openlng for the purpose of closing the latter. Disk 3, as shown, is also provided with a port 6, said port leading from its inner face to the opening 4, the purpose of which is to form a communication between the vent pipe 10 and a tubular member 20 extending downwardly through the device, whereby air, when required, may be supplied to the intenor of the receptacle. In some cases, however, as hereinafter referred to, the port 6 and vent pipe 10 may be omitted.

The reference character 7, denotes a peripherally threaded plug which engages with the threads of the wall of the opening 4, for the purpose of normally closing said openmg 4, and port 6. The plug 7, is adjustable,

and has its lower end reduced as at 8, and I which is adapted, when the plug 7 is adj 11sted inwardly, to engage a stop member 9, whereby the lnward movement of the plug 7 Wlll be arrested.

Depending from the disk 3, is a vent pipe 10, having its lower end in the form of an L, as at 11 and its upper end funnel-shaped, as at 12, and which is secured to the inner face of the disk 3, as at 13. The stop arm 9, 1s arranged within the funnel-shaped portion 12, as well as, being secured therewith, at a point in the line of inward travel of the plug 7.

The upper face of the plug 7 is grooved as at 14, for the purpose of receiving the end of a suitable instrument or tool, hereinafter referred to, to adjust the plug 7.

The upper face of the disk 3, has formed integral therewith a pair of upwardly extending studs 15, and each of which is formed with an opening 16. The function of the studs 15 will be presently referred to.

The bung element further includes a flanged closure cap 17, having pockets 18, for the reception of the studs 15, when the cap 17 extends within and has threaded engagement with the threads of the opening 2, as shown in Fig. 2.

The disk 3 is of less thickness than the depth of opening 2, and by such an arrangement, when the disk 3 is mounted in position to close the opening 2, as illustrated in Fig. 2, the cap 17 can extend in said opening and engage with the threads of the wall thereof. Interposed between the flange of the cap 17, and the head 1 is a gasket 19.

20 designates a tube preferably peripherally threaded, as shown, extending downwardly through the device and adapted to have its lower end connected with the bung element. Said tube is designed for the purpose of supplying air to the interior of the receptacle when required and also for the purpose of connecting or coupling the bung element to the tap device proper or to the discharge element thereof, as hereinafter referred to. 21 designates a spider located at the outer or upper end of the tube 20. Extending down through the tube 20, is an adjusting tool 22, for the plug 7. Said tool 22, has its lower end widened and flattened, as at 23, for engagement with the groove 11, as shown in Fig. 1, for the purpose of adjusting plug 7. The outer end of the tool 22 has a handle 24.

The discharge element comprises an elbow coupling 25, provided with an outwardly extending interiorly threaded nipple 26, which opens into the coupling 25. The tube 20 extends through the nipple 26, el-

bow 25, and has a threaded engagement with the threads of the nipple 26.

Detachably connected to the upper end of the coupling 25 is a pipe line 27 provided with a faucet or discharge valve 28.

Detachably connected to the lower end of the coupling 25, is a hollow cylindrical member 29, provided at its inner portion with peripheral threads 30. At the inner end of the member 29, an inwardly extending annular flange 31 is provided, having diametrically opposed openings 32. The member 29, in proximity to the flange 31 is formed with diametrically opposed outlet slots 33.

The flange 31 forms a clearance or opening 34, for the passage of the tube 20, for a purpose to be presently referred to.

The openings 32 are adapted to receive the studs 15 of the bung element when the discharge element or the tap device proper is applied to the bung element.

The studs 15 extend through the openings 32 and as illustrated, pins 35 may be passed through the openings 16 of the studs 15, thus connecting the discharge element and the bung element together. The discharge element and the bung element, however, may be connected or coupled together by the tube 20 without the employment of the pins 35. This latter connection may be made by entering the lower threaded end of the tube 20 in the threaded opening 4 of the bung element 3 after the plug 7 has been adjusted downwardly sufficiently to allow the threads of tube 20 to engage threads of the openings 4.

The bung element is adjusted inwardly by a rotative movement imparted to the discharge element or by turning the tap device proper, it being understood that when the member 29 is in the position shown by Fig. 1, the studs 15 of the bung element will be entered in the openings 32 of the flange of element 29; therefore, a bodily rotation of the element 29 will cause the bung element to move in unison therewith, whereby the parts may be moved'into the position shown by Fig. 4.

In some cases, particularly where the receptacle contains high gravity gasolene, it is unnecessary to introduce air to the interior of the container in order to discharge the contents; consequently, the air supplying means may be omitted. I

Assuming that the vent pipe 10 and the adjustable plug 7 are employed, Fig. 2 shows the relative position of the parts for shipping the container. To discharge the contents, cap 17 is removed, after which the assembled tap device is applied to the bung element with studs 15 of the bung entered in the openings 31 of the member 29 and the threaded portion 30 of said member engaging the threaded wall of opening 2 of the container. Plug 7 is then adjusted inwardly sufliciently to permit member 20 to engage the threaded wall of the opening 4, thereby connecting or coupling the discharge and bung elements together. A rota tion of the discharge element will advance the bung element and the lower end of the discharge element into the container, thereby bringing the outlet slots 33 below the head 1, and forming a communication between the interior of the container and the discharge element. The container or barrel is then inverted, and valve 28 of the pipe line opened, thereby forming an open passage for vapors and liquids from the interior of the barrel to the slots 33 and element 29.

In the event that it is necessary to admit air to the interior of the container for the purpose of discharging its contents, plug 7 is moved inwardly by tool 22 a distance suificiently to uncover port 6 of bung element 3, thereby permitting air to reach the interior of the container through pipe 20 and vent pipe 10. I

The manner of setting up the tap when opening the bung hole of the barrel will prevent any possibility of waste during the tape ping operation.
